Core Tip
Core tip: In this study, we designed a disposable graduated biopsy forceps and used the forceps as “scale plate” to measure the polyp size. We enrolled 133 polyps from 119 patients and found that the accuracy of the visual estimation for a polyp size was low but could be improved if the disposable graduated biopsy forceps were used as a scale. Though some slight deviation still existed for estimation of polyps over 2 cm, the difference was not significant and did not affect treatment.
